Visualization Best Practices guide

1. Avoid the use of quick filters on dashboards to improve load times. Use cross tabs, heat maps and highlight table filters....sometimes pie charts work for this purpose as well.

2. Keep dashboards to 4 panes and imagine a Z pattern of importance from upper left to lower right.

3. Don't build grids or pivot-table-looking dashboards. Use visual analytics and bring details in on demand via filter actions, jump filters, annotation or customized tool tips.

4. Pimp your tool tips at the end. If you don't, you will create more work for yourself.

5. Use color sparingly and never more than 2 ways in a single dashboard. Preferably one.

6. Avoid pie charts for one to many comparisons.

7. Use bullet graphs or bar charts.

8. Don't repeat the same chart type in dashboards - it’s boring.

9. Leverage data blending for ad hoc analysis to add meaning and WOW factor.

10. Strive for a high data to ink ratio - eliminate color, shape, size or text that doesn't add information or is redundant.

Tableau Mobility : How can we do it ?

In Tableau, you do not have to do anything special to make a dashboard mobile. Simply publish to Tableau Server like you always have, and Tableau will detect if you’re using the Mobile app. You even get the native touch experience if you go to Tableau Server from your mobile browser, without the app at all.

Ease of use is the single most important aspect of mobile business intelligence. When you’re on the go, you need to be able to get to the data you need with a few taps.

Filters: Tableau’s controls such as filters, parameters, sliders, scrolling, and zoom & pan, are specially built to interact with your fingers. For example, tapping a filter pops a large, touch-optimized quick filter. And for long filters, there is scrolling inside the filter.

Views: Views themselves are touch-optimized with dynamic scrolling. Simply swipe to scroll through a long customers list, for example. Or pinch & zoom in a map.

The two major approaches for Mobility in Tableau

Security

Mobile business intelligence must be secure. With the Tableau mobile solution, security and metadata continues to be managed by Tableau Server. This means you can enforce your existing security protocols and integrate with ActiveDirectory via Tableau Server.

And if an employee loses their iPad or Android tablet, simply disable their Tableau Server account and give them a new one. No data other than descriptive data about a workbook (like the publisher, data modified and name) are stored on the device, so you can keep your data secure even while it’s mobile.

Using Desktop excel file as Live data Source for Tableau Server

Thanks Jonathan Drummey for the steps

The order of setting up a live Tableau Server connection to a file data source such as Excel, Access, or text file via a workbook (in other words, *not* using Tableau Data Server) is:

0) If Microsoft Office is not installed on Tableau Server and you are connecting to Excel or Access files, you will need a driver from the list in Drivers & Activation | Tableau Software. Note that this requirement will go away in many cases for Excel files in Tableau 8.2 that can use the new Excel connection type in 8.2.

1) Set up your Tableau Server so that the user Tableau Server runs as has access to wherever you are putting the Excel, Access, or text files to use as data sources.

2) In Tableau Desktop always use the UNC path like \\localhost\pathname rather than C:\pathname. If you didn't do that at the beginning, you can always edit the connection later, which is better than replacing the data source because if you do the latter then you'll lose colors & aliases.

3) When publishing to server, make sure you *uncheck* "Include External Files". If you don't do this, you'll be scratching your head later when the data doesn't update. If you didn't do step 2 or step 1, when you publish as Tableau is rendering the viz in the preview window Tableau will spit errors at you saying it can't display the viz. Note that Tableau only does that for the data sources required for the viz, so if you have data sources A and B, and the preview viz uses A but B isn't available, the publishing will work fine and you won't get the error until someone on Tableau Server tries to access a worksheet or dashboard that uses data source B.
